Hi,
Vauxhall Zafira A 2004 2.0DTi Y20DTH engine.
Anyone know if the EGR valves are electronic on this engine i.e. what opens and closes them? Mine is same as attached pic and does have a multiplug going into it.

Do they open gradually as engine revs increase or are they just either fully open or fully closed?
I'm just trying to understand how these work and why they fail so regular....in the 4 years I've had the car I've had one replaced under warranty, one replaced I had to pay for, the last one cleaned (which lasted about 6-7 months) and now have the same problem again....my independant garage has cleaned again but it still hasn't sorted the problem....I fear yet another replacement coming.
Cheers
